The main aim of this thesis was to unravel the signaling and regulatory networks that drive tumor cell migration during breast cancer metastasis.

Breast cancer is the most common cancer in women worldwide. Metastasis, the process by which cancer cells spread to other parts of the body, makes treatments less effective. It is important to unravel the mechanism of metastasis.

The objective of this study was to investigate the expression and function of GRHL2 in different breast cancer subtypes.

Metastasis is responsible for over 90% of cancer-related deaths and arises from the ability of a small subset of tumor cells to detach from the primary tumor, overcome multiple biochemical and mechanical barriers, disseminate through the body, and colonize distant organs.

Invasive lobular carcinoma (ILC) is the second most common type of breast cancer.

The spindle-assembly checkpoint (SAC) is a safety mechanism which secures accurate chromosome segregation during mitosis.

In this thesis, we will utilize embryonic zebrafish tumour models to understand the interaction between engrafted human cancer cells and macrophages from the host, test drug administration modalities and anti-cancer efficacies of newly-developed PDT and PACT compounds, and test a light-triggered liposomal…

The clinical potential of applying synthetic lethality to cancer treatment is famously demonstrated by the BRCA1/PARP1 paradigm: a tumor specific defect in BRCA1 – a component of the DNA double-strand break (DSB) repair pathway homologous recombination (HR) – results in a remarkable sensitivity to PARP1…

To improve treatment of breast cancer patients it is important to understand all stages of breast cancer from initiation to in situ disease and progression to invasive disease. In this thesis we use intraductal injections of patient derived tissue to model ductal carcinoma in situ and invasive breast…

Breast cancer (BC) is a clinically and biologically heterogeneous disease.

Drug development is hampered by the limited predictive value of conventional 2D culture systems, which fail to recapitulate the complexity of the disease microenvironment and contribute to high clinical attrition rates.

The molecular mechanisms that instigate a healthy cell to become malignant are fueled by (epi)genetic alterations in so-called driver genes.

This thesis investigates how cell shape and collective behavior influence the dynamics and structure of biological tissues, which are crucial for understanding processes like embryonic development, tissue regeneration, and metastasis.

To improve cancer treatments, personalized medicine approaches have aimed to identify exactly which mutations are driving tumor development in a given patient and specifically target these mutations using precision therapies.

​Hoe verwerkt ons brein prikkels en informatie? Waarom is ons brein zo gevoelig voor fake-news? Doordat het leven van jongeren steeds meer online plaatsvindt, worden zij ook vaker blootgesteld aan fake-news. Valse informatie kan schadelijk zijn voor de gezondheid en het welzijn van jongeren. Om dit…

This thesis represents a comprehensive investigation into the control of cancer stemness and metastatic initiation using a combination of advanced zebrafish xenograft models and in vitro assays.

In this thesis, we aim to shed light on the diverse and often opposing roles of integrin α3β1 in cancer.

Triple-negative breast cancer (TNBC) is a subtype of breast cancer characterized by limited treatment options and unfavorable clinical outcomes. Therefore, the research described in this thesis focused on the exploration of novel targeted therapies for TNBC.

Pancreatic ductal adenocarcinoma (PDAC) is among the cancers with the highest mortality rate, despite a relatively low incidence.

Triple-negative breast cancer (TNBC) constitutes a small subtype (~15%) of breast cancer, but causes the majority of breast cancer-related deaths.

Is het brein van de rechter in staat om bewijs (DNA, camerabeelden) zo te interpreteren dat de waarheid wordt gevonden? Wat betekenen afwijkingen in het brein van de verdachte voor diens toerekeningsvatbaarheid? Kunnen we het brein van veroordeelden zo beïnvloeden dat ze niet zullen recidiveren? Deze…

The research described in this thesis focused on identifying novel drug targets and synergistic combinations for triple-negative breast cancer (TNBC), a virulent subtype of breast cancer with a dismal prognosis and limited therapeutic options.

Onderzoekers werken al eeuwen aan een atlas van het brein. Maar zelfs in 2017 zijn sommige hersenstructuren nog niet in kaart gebracht, met name in de hersenstam. In dit paper hebben we de test-hertest betrouwbaarheid gemeten van de enige MRI-scan die onderzoekers in staat stelt om de locus ceruleus,…

In this thesis, we used genetically engineered mouse models to identify genes and pathways that are involved in ILC formation and in the development of resistance to FGFR-targeted therapy.

G protein-coupled receptors (GPCRs), one of the largest families of membrane proteins, are responsive to a diverse set of physiological endogenous ligands including hormones and neurotransmitters.

Death in all types of melanomas is generally caused by metastasis. Uveal melanoma (UM) is the most common intraocular melanoma, there are currently no (patient-derived) animal models that faithfully recapitulate metastatic dissemination of UM.

Paniekstoornis hangt samen met veranderingen in het brein, zowel in kinderen en adolescenten als bij volwassenen. Dat is de voornaamste uitkomst van de grootste hersenstudie ooit naar paniekstoornis.

In this thesis, we used genetically engineered mouse models and a variety of cell-culture based assays to identify genes and pathways that are involved in the development and treatment of invasive lobular carcinoma (ILC).

Traditional drug discovery approaches have been hampered by (in vitro) cell-culture models that poorly represent the situation in the human body.

This thesis focuses on using liposomes in two different treatment strategies; vaccination (or immunotherapy) and delivery of a small molecule, and in two different disease models; cancer and atherosclerosis.

De activiteit van het brein verandert naarmate mensen ouder worden, wat kan leiden tot cognitieve achteruitgang. Door hersendata van muizen en mensen te meten en vergelijken, wil de onderzoeker begrijpen hoe tijdens het ouder worden de ruizigheid van ons brein verandert en keuzegedrag beïnvloedt.

Eiwitten remmen die een rol spelen bij de groei van agressieve kankercellen, dat is het plan van professor Bob van de Water en zijn team. Zij ontvangen hiervoor ruim 700.000 euro van KWF Kankerbestrijding. Onderzoeker Maaike Vreeswijk en patholoog Danielle Cohen zijn aangesloten vanuit het LUMC.
